Carbon Capture for Enhanced Oil Recovery in Niger Delta: A Case Study of Okoto/Okpoputa Field in Offshore Niger Delta

摘要

Carbon capture for enhanced oil recovery is a proven technology that holds the promise of increasing oil reserves, reducing greenhouse gas (GHG) emissions, diminish the concerns associated with the release of cocktail gases from gas flaring and reduce hostility in host communities. In this work, we considered the Okota/Okpoputa field in Offshore Niger Delta and covered areas of interest such as the post combustion capture using monoethanolamine (MEA), prognosis of storage site, increase production pressure, economics of the capture and assessment of the risk of leakage. With about 80million tonnes of CO2 captured annually from flared flue gas, the CO2- enhanced oil recovery will yield 20-40% Original Oil in Place (OOIIP), and this will translate to a savings of $ 474,500,000 excluding commercial sales of CO2.
